' UNITED 1 JAN woLsKI, or; enrolle .mirrors-*1 TRIP-OPERATED RAILWAY-sinner! To all whom it may Concern Be it known that I. JAN WoLsKr, a subject of the Czar of Russia, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Trip-Operated Railway-Switches, of which the following is a specification. I

This invention relates to new and useful improvements in trip operated railway switch. j

The primary object of the invention is to provide a shiitableswitch'tongue adapted tojbe actuated from an approaching car and then returned to its normal position after the car has passed the switch tongue.

A further object of the deviceis to provide a normally closed sidingswitch adapted to be closed by an approaching car for allowing its passage upon the 'maintrack and further providing for a return. of the siding switch to its opened position after the car has passed the same. H

A still further object is to provide a railway switch actuator especially adapted for street railways and arranged for manipulation by an approaching and a receding car by the proper positioning of a foot lever upon the moving car. y 2

With these general objects in View and. others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arvrangement of parts to be hereinafter fully described, illustrated in the accompanying drawings and pointed out inmthe appended claim. I In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views: Figural 1s a top plan view of a portion of a railway with the present invention installed thereon but with the covers for the mechanism casings removed. Fig. 2 is a vertical central longitudinal sectional View thereof taken.

shifting. block 20; w hich blockiis rigidly" at- C lThe' post 17 is also provided with along.arini 22 its free end and extending through a pipe or conduit 88 positioned beneath the road bed between the casing and the casing 14, which latter casing, is .entered by ,the said rod 23. A rocking shaft 24 is horizontally journaled within the casing 14 and is pro-v vided with a short arm having its upper free .end pivotally' connected to the end of the rod 23 which is within the casing 14. The post 17 and arms 18 and 22 will'beunr .tarily called a rocking lever, and as .before stated, this rocking lever is connected by therod 23 to the arm 25 on the rocking shaft 24. A trip block 26 projects through an opening 27 in the removable cover 28 of the casing 14 and has its bottom projection 29 pivoted to an arm 30, which arm is pivoted at substantially its center to a bracket 31 upon the bottom 32 of the said casing while a long arm 33 of the rocking shaft 24 freely rests upon :the free end of the arm 30. By this arrangement it will be seen that a train or acar upon the main track moving in a direction indicatedby the arrow, a portion "of the fioor 34 ofsucha car being indicated in Fig. 2, may be readily provided with a means for depressing the block 26 and thus shifting the-tongue12to its closed'position. Such a means is herein illustrated in the formof a foot pedal 35 upon a spring pressed normally elevated vertically posi tioned trip rod36, which rod is provided at its lower end with a roller 87 and being normally positioned so as to freely pass above the block 26 may be readily depressed by the footof the motorman upon the car for bringing the same in contact with the block 26so as to depress the said block when the car is either moving or standing still. By depressing the block 26 the arm 30 is actuated and thereby turns the rocking shaft 24 and moves the rod 23 for exerting a pull upon the long arm 22 of the post 17 and also pulling the link 19 by means of the arm 18 which moves the block 20 inwardly and shifts the tongue 12 to its closed positionas shown in Fig. 6. A lever 39 is pivoted within the casing 15 and provided with an upturnedend flange 40 adapted to.

engage over the block 20 and retain the same with the switch tongue in its closed position'as shown in Fig. 10, it being noted that a leaf spring 41 holds the lever 39 resiliently in a normally elevated position, while an expansion spring 42 having one end abutting a lu'g 43 within the casing 15 has its opposite end forcibly'engaging the inner face of the block 20 and normally holds the block in its outer position and with the switch tongue QPQI The releasing mechanism provided in the casing 16 consists of a horizontally jourbracket 47 of the said casing and having at its opposite end a vertically extending rod 48 hingedthereto while a trip block 49 is mounted upon the upper free end of the rod 48 and extends through the opening 50,01 the removable cover plate 51 of the said casing 16. The rod 44 has an upwardly extending arm 52 which arm is pivotally connected at its free end to an arm 53 of a journaled rod 54 within the casing 15 by means of a connecting wire 55. The said wire 55 passes through the. conduit 56 positioned between the casings 15 and 16. The rod 54has an angularly extending finger 57 which is hinged as at 58 to an intermediate portion of the lever 39.

With the switch tongue in its closed position and engaged by the flange of the lever 39, the depressing of the roller 37 into contact with the block 49 afterthe passage of the car past the switch will depress the rod 48 and tilt the lever 46 for upwardly moving the arm and partially rotating the rod 44 which thereby exerts a pull upon the wire by means of the arm 52 and in turn imparts a partial revolution to the rod 54 and moves downwardly the finger 57 for downwardly tilting the flanged end of the lever 89, so that the block 20 is released from the flange 40 and the spring 42 returns the block with the switch tongue to its normal open position. A leaf spring 59 carried within the casing 16 bears against the arm 52 and normally holds the arm 45 against the lever 46 and with the block 49 normally elevated. The casing 15 being provided with a removable cover 60 has a slot 61 therethrough for the sliding reception of the switch tongue pin 21.

By this detailed description of the complete invention, the operation thereof will be apparent and the manner by which a person upon the car may throw the switch to its closed position when approaching the same and may release the switch for returning it to its open position after having passed the switch. It will also be seen that a train approaching the switch may take either the direct track or the switch track.

While the forms of the invention herein illustrated are the preferred embodiments rocking lever linked to said block, a rock lever and a trip block operatively connected 10 shaft, an arm upon said shaft, a connecting to said releasing means. rod between said arm and rocking lever, 'a In testimony whereof I aflix my signatiipfiplockdopegativeiy connected to said rgck ture in presence of two witnesses.
